Police have charged Mark Eric Hayes in connection with a home invasion in which a gun was put to the head of an eight-year-old girl.
Hayes, 24, is charged with two counts of aggravated robbery.
He was arrested after the female victim said she spotted his picture on Facebook.
The incident happened June 28 at W. 15th Street Court at the residence of a woman who said she sells candy, drinks and cigarettes from her apartment. She said there was a customer named "Clown" and just after he left, there was a knock on the door.
She said a black male entered and tried to buy a drink with a $20 bill. She said she told him she had no change. She said the man then locked the front door and produced a large, semi-automatic handgun.
She said he told her to "give me everything you have." She said she told him she did not have anything.
The woman said the robber then put the gun to her daughter's head. She said he pushed the daughter down some steps and ran after her.
She said three other black males then entered the apartment and they carried off two flat screen TVs and loaded them into a silver Audi.
Police said the four men involved are allegedly members of the Gangster Disciples gang.
Several neighbors reported seeing the Audi. The gunman was described as 5'10" with short hair and a stocky build.
About a week later, the robbery victim came to police headquarters and said she had learned from Facebook that the gunman goes by the name Mark Major. Police said Mark Major is a name used by Hayes.
The woman was shown a lineup and she said she was almost positive that Hayes was the gunman. The daughter was shown the pictures and she picked out Hayes.
Hayes has a lengthy record with charges that include drugs, aggravated assault and gun violations.
